Dro

[Tanya Shivari]

HyDROponically grown marijuana, i.e., homegrown. Pot grown indoors in hydroponic chambers, which regulate light, humidity, and temperature. Usually a higher, more pure quality of weed than that found elsewhere. Whether there are additives such as cocaine in it is a secondary matter - ask honest questions of your dealer. When in doubt - dont buy.

The term means hydroponic, as in hydroponically grown weed.
There are male and female marijuana plants, when you let a male release pollen onto a female plant the female will produce seeds in her buds. If there are no male plants around the female plant will still produce her buds, but there will be no seeds inside, which gives the plant a lot more energy to produce THC. This is commonly referred to as hydro, though to grow seedless bud you wouldnt necessarily need to use hydroponics.
Hydroponics systems work by filling a bucket filled of hydro ton (airy rock pellets) with nutrient enriched water for a few seconds every few minutes. The plant uses little energy to grow roots as it doesnt need to expand to get nutrients it needs, and can use its energy to grow leafs and buds.

slang term for high grade weed grown without any seeds. weed grown in a hydro medium or in soil as long as its been properly cared for and the male plants have been removed the buds will grow big fat chrystal like. most of the dro sold on the streets hasnt necessarily been grown in a hydroponic medium, but the streets have no idea because they cant tell

Although originating from the word hydroponic, marijuana no longer has to be hydroponically grown to be referred to as dro. Rather, its a general term for standard, good weed, in other words that which is better than mids and schwag, but not as good as headies and crazy strains.
